2026-June-1 Service Incident
Incident
Report for Sauce Labs
Postmortem
Dates:
Monday, June 1st 2026, 13:06 UTC - 15:42 UTC.
What happened:
Customers served by the US-EAST-4 region were unable to authenticate or start new test sessions because an incomplete TLS certificate chain was deployed to the core directory services.
Why it happened:
A certificate extraction script defect silently truncated the certificate chain after the certificate authority transitioned to a longer hierarchy.
How we fixed it:
Reverted the certificate rotation and re-applied the previous known ,good certificate to restore authentication services.
What we are doing to prevent it from happening again:
Implementing pre-deployment certificate chain validation, adding active monitoring, and fixing the script's chain-length limitations.
Resolved
After taking remedial action, access to the US-EAST data center is fully restored. This incident is resolved.
Monitoring
Access has been restored to the US-EAST data center. We are monitoring.
Update
We have identified the root cause and are working on implementing a fix.
Update
